Forms of potassium, nutrients status and their interrelationship with total and available nutrient were investigated in forty-five soil samples representing fourteen profiles from five districts (Typic Haplusterts) of Central and Western Vidarbha region of Maharashtra. The available, water soluble, exchangeable, non exchangeable and lattice K contributed 1.97, 0.12, 1.88, 11.25 and 86.76 per cent towards total soil K in the given soils. The soils of Wardha, Nagpur, Chandrapur and Bhandara districts were slightly calcarious neutral to alkaline in reaction and the soils of Gondia district was non calcarious and sightly acidic in reaction. The Central Vidarbha soils are clay in texture having high CEC and organic carbon content. Where as the soils of Eastern Vidarbha is clay loam, sandy clay loam, low in CEC and organic carbon content. No definite trend was observed in the forms of potassium except exchangeable and available K they are decreased with increase in depth. The available K, exchangeable K, total K and lattice K, influenced by total N (r=0.3268*, r=0.3122*, r=0.2950, r=0.3079*) respectively. The available K and exchangeable K is also affected by available N (r=0.9784**, r=0.9773**) respectively, in Vidarbha region. In Central Vidarbha available and exchangeable K influenced by total and available N respectively. In eastern Vidarbha the available K and exchangeable K influenced by total S and available N.Keywords

The subsurface drainage system was installed on farm with corrugated perforated PVC pipes on 8.81 ha of salt affected soils at Agril. Research station K. Digraj Dist-Sangli (M.S.) in December, 2002 to study the effect of subsurface drainage system for improvement of salt affected - waterlogged soils. The results revealed that the pH, ECe, SAR and ESP of soil in SSD with synthetic envelope, coarse sand filter and synthetic envelope + coarse sand filter were decreased in monsoon and winter season but slightly increased during the summer season. This indicates that the improvement in salt affected soils due to subsurface drainage and gypsum application within a period of one year.Keywords

The field experiment was conducted to study performance of different filter (envelope) materials in subsurface drainage (SSD) system. The results revealed that the water table decline, drain discharge, drainage coefficient and hydraulic conductivity were maximum, whereas EC and SAR of drain water were lowest in SSD system with coarse sand filter over SSD system with coarse sand + nylon sleeve and nylon sleeve alone.Keywords
